Hi Rado
Ya. Now it's working great.
Yesterday and today I completely spend my time reading AWK book.
I covered up to control statements. Still your script is looking complex to me though I'm able to understand somepart.
But your are right in one thing I'm learning so much even though it is taking lot of time.

Thanx for the help and suggestionsSmilie

Input
Code:
X1	84	140	-	4,10,4	0,36,52
X1	20	110	+	5,10,5	0,35,90
X1	84	140	-	4,10,4	0,36,52

output
Code:
X1	136 140		84	140	-	4,10,4	0,36,52
  	120 130
  	84 88

X1	20 25		20	110	+	5,10,5	0,35,90
  	55 65
  	110 115

  	136 140
X1	120 130		84	140	-	4,10,4	0,36,52
  	84 88
X1	136 140		84	140	-	4,10,4	0,36,52
  	120 130
  	84 88

Needed and correct output

Code:
X1	136 140		84	140	-	4,10,4	0,36,52
  	120 130
  	84 88

X1	20 25		20	110	+	5,10,5	0,35,90
  	55 65
  	110 115
X1	136 140		84	140	-	4,10,4	0,36,52
  	120 130
  	84 88

Some where in the code is printing double values for "-".
The bold letters are creating mess. As you can see X1 is one row down as well as its unnecessary duplicate

I solved it. Please don't post any answer for this question

Code:
$ awk 'NF {
  sec = $2; fifth = split($5, _fifth, ","); sixth = split($6, _sixth, ",")
  counter = rec = ""; key = $1; flag = $4; sub(/[^ \t*]*/, "")
  dummy = sprintf("%*s", length(key),x)
  for (i=1; i<=sixth; i++) {
    second_third = sec + _sixth[i] FS _fifth[i] + sec + _sixth[i]
    third_second = sec + _sixth[i] FS _fifth[i] + sec + _sixth[i]
    if (flag == "+")
      rec = rec ? rec RS dummy OFS second_third : key OFS second_third OFS $0
    else if (flag == "-")
      rec = rec ? rec RS dummy OFS third_second : key OFS third_second OFS $0
  }
  print (flag == "+" ? rec : rec)
  }' OFS='\t' ORS='\n\n' input.txt
